摘要 关联规则采掘是数据采掘中重要的研究课题。针对当前关联规则采掘中可能产生许多无效关联规则的问题 ,分析其原因 ,提出在衡量标准中增加有效度 ,并给出了有效度的定义。根据有效度的大小 ,将关联规则分为正关联规则、无效关联规则、负关联规则 ,提出了新衡量标准采掘关联规则的算法 ,并用 Visual Fox Pro进行了试验。实验表明 ,新方法能明显减少无效关联规则的数目。 Mining association rules are an important topic in the data mining research. The reasons for many invalid rules in mining association rules are analyzed. The validity is defined and added to the judgment criterion. According to the value of validity, association rules are classified into positive, invalid and negative association rules. An algorithm of new judgment criterion in mining association rules is presented and tested with Visual FoxPro. The test results show that the method can obviously reduce invalid association rules.
